POCKET CHECK PROTECTOR Filed July 24, 1946 Patented D 30 19 Application July 24,

1 Claim.

This invention relates to checl: protectors especially designed for pocket or personal use.

An important object of the invention is to provide a check protector embodying cooperating rollers having teeth that perforate a check, when the check is drawn therethrough, the construction of the check protector being exceptionally simple, to reduce the cost of production to the minimum.

Another important object of the invention is to provide a check protector of this character wherein the body portion thereof is constructed of spring wire material having flat outer surfaces and rounded inner surfaces, the flat outer surfaces affording an exceptionally convenient gripping surface to prevent twisting of the check protector when in use, while the inner curved surfaces of the body portion permit the check to slide freely therethrough.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing Figure 1 is an elevational view of.a check protector, constructed in accordance with the invention.

'Figure 2 is an edge elevational'view thereof.

Figure 3 is a fragmental sectional view taken on line 3-3 of Fig. 1.

Figure 4 is a sectional view taken on line 4-4 of Fig. 1.

Referring to the drawing in detail, the device comprises a bodyportion ll including a length of heavy wire material bent upon itself to provide a substantially U-shaped structure.

The free ends of the body portion are reduced, and offset with respect to the inner surface of the body portion, providing supporting shafts 8 on which the perforating rollers I operate, the perforating rollers I having their surfaces knurled or roughened, so that when they are pressed into engagement with a piece of paper, such as a check or the like, the knurled surfaces will cut or perforate the surface or sheet of paper moving therebetween.

As clearly shown by Fig. 3 of the drawing, the rollers l' are su ported on the b ll bearings 8,

the inner ends of the rollers contacting the shoulders 9 to restrict inward movement of the rollers with respect to the body portion.

The shafts 6 are formed with threaded bores in the ends thereof, which bores accommodate the screws Ill that pass through the disks H, the disks ll being of diameters to extend over the outer ends of the rollers, to secure the rollers in position on the body portion.

As shown by Fig. 4 of the drawing, the outer surface of the body portion is flattened as at l2, while the inner portion thereof is rounded as at H, the flattened surface l2 providing a gripping surface whereby the device may be gripped and operated. without the device slipping in the hands of the user. Due to the curved inner surface of the, body portion, it will be seen that this curved surface will contact with the check or piece of paper being moved through the device, and ofier little resistance when the check is being drawn therethrough.

In the use of the device, a check to be perforated or protected, is positioned between the cooperating rollers, and the body portion is gripped by the operator to cause the rollers to move into cutting relation with respect to each other. As the device is pulled along the check or piece of paper, it will be obvious that the check or paper will be perforated to prevent alteration of the check by rubbing out to change the amount given on the check.

What is claimed is:

p In a check pr tector, a substantially U-shaped body portion f0 med of a length of wire material, cooperating \perforating rollers mounted on the free ends of the body portion and adapted to perforate a check moved between the rollers when )the rollers are pressed into engagement with each other, the outer surface of the body portion being flattened, and the inner surface of the body portion being curved.
